. Application M615, 1949, Serial No. 99,172

The present inventionrelates to improvements in a mechanical toy deviceof theftype lhaving wing sections that maybe given an oscillatory motionby'applying pressure toa pair of hamdles to which the wing sections arepivotall'y at tached.

An object of this invention is to provide a mechanical toy device whichis designed to resemble birds, bats, butterflies or other flying insectsand is similar to the mechanical toy shown in my copending applicationSerial No. 98,229.

A further object of the invention is to provide a mechanical toy devicewherein compression of a pair of pivoted handles will cause the wingsections attached to the handles to move upwardly and to provide aspring means to cause the wing sections to move downwardly when thehandles are released, thus providing a motion similar to the wingmovements of a flying bird or insect.

With the above and other objects and advantages in view the inventionconsists of the novel combination and arrangement of parts hereinaftermore fully described, claimed and shown in the attached drawings inwhich:

Fig. 1 is a bottom plan View of the invention with the wings in upposition and with parts broken away;

Fig. 2 is a top plan view with the wings re moved and the remainingparts in position as shown in Fig. 1;

Fig. 3 is a view similar to Fig. 2 with the parts in normal or downposition;

Fig. 4 is a side elevation of the parts as shown in Fig. 3;

Fig. 5 is a side elevation of the parts as in Fig. 2 with some of theparts broken away;

Fig. 6 is a sectional view on the line 6-5 of Fig. 3;

Fig. 7 is a sectional view on the line 7-! of Fig. 2;

Fig. 8 is a sectional view on the line 8-42 of Fig. 2; and

Fig. 9 is a view with the parts shown as in Fig. l with some parts insection and other parts in elevation.

Referring more in detail to the drawings wherein a preferred embodimentof the invention is shown to include a pair of similarly formed handlesl0 and II which are pivotally connected together intermediate of theirends by the pivot pin I2. To limit the inward movement of the outer endof the handles it and H, the handle ll is provided with a stop means 93while the handle H is provided with a stop means l4. As shown in Fig. 2,the stop i3 is provided with a 101mm;- 01. s-#124) concave face whilethe stop H! is provided with a convex face, and the engagement of thesetwo faces limits the closing movement of the handles Hi andl l uponreleasing thereof by the operator of the handles. Rubber pads may beattached to the faces of the stops it and F4 to act as shock absorberswhen the handies are moving to closed position. The stops also tend tohold the handles more rigidly when the handles are in closed position.

The bird or simulating wings comprise a pair of large sections 15 and i5respectively, which are similar in shape and contour to each other and apair of small sections is and I6 respectively, which are also similar toeach other in shape and contour, but are of smaller area than thesections l5 and I5.

U-shaped reinforcing element ll having a base It and a pair of stems l9and IS respectively,

. extending outwardly of the base l 3, are attached to the Wing sectionl 5 by any well-known fastening means ill]v Each stem at its outer endis provided with a bearing support 2| and short extensions 22 and 22'respectively, extend from the bearing supports 2l at an acute angle tothe stems l9 and l9 respectively. A similar U- shaped reinforcingelement 23 having a base 24- and a pair of stems 25 and 25'respectively, extending outwardly of the base 24 are also attached tothe wing section E5 by any well-known fastening means 20. Each stem atits outer end is provided with a bearing support 26 and it will be seenin Fig. 1 that the bearing supports 26 are positioned intermediate ofthe bearing supports 2! of the reinforcing element il'. Short extensions21 and 21 respectively, extend from the bearing supports 26 at an acuteangle to the stems 25 and 25' respectively. The reinforcing elements Hand 23 are therefore similar in shape except that the element 23 is of asize to permit the stems 25 and 25 respectively, thereof to bepositioned intermediate of the stems E9 and iii of the element [1.

A through bolt 29 is passed through the bear ing supports 2! and 26 toloosely pivotally or hin edly connect the reinforcing elements H and 23for oscillating motion in relation to each other, as shown in Fig. 1.

The outer ends 352 and 31 respectively, of the handles It and H arepositioned at an angle to the remainder of the handle, as shown in Fig.4. Secured to the portions 30 and 3! respectively, in spaced relation toeach other are the eye bolts 32 and the eye bolts 32 on each handleloosely receive a through bolt 33. The outer ends of the shortextensions 22 and 22' of the element I! are provided with bearingsupports 34 and 34' respectively, which are loosely journalled on thethrough bolt 33 on the handle H. The outer ends of the short extensions2"! and 21 of the element 23 are provided with bearing supports 35 and35 respectively, which are loosely journalled on the through bolt 33 onthe handle H]. A coil spring 36 is coiled on the through bolt 29 and oneend 31 thereof extends in one directionto engage the through bolt 33 onthe handle Il while the other end thereof extends in the oppositedirection to engage the through bolts 33 on the handle l0.

With the spring 38 mounted on the through? bolt 29 the spring may behidden from view by a flexible cover joining the wing sections or by anyother suitable means. Thus by using at coiled spring on the through bolt29 a spring will not have to be mounted on the handles. The coiledspring, by having the ends thereof overlap or' engage the through bolts33, providesa' posttive closing force that is directly applied to bb'thwing sections and also directly to the handles;

In the operation of the device, pressured!- ap-'- plied to'the' lowerends of thehand-les a -hdn'd of the'opera tor. The pressure ontheends-ofi'th'e handles will cause the upper ends to spread-wid'ei Thisaction will cause the wing sections 15' and I5 to move upwardly andplace a tensionon'the' ends of the coil spring. When pressure is"- re=-leased on the ends of the handles the tension' of thecoil spring 36 willquickly movethe wingsecti'ons' I 5 and I5 downwardly int'o no'r'mal tionand the upper ends of handles into closed positionas permitted by thestops it and I4.-

Repeated pressure on the handles and the re lease thereof will cause thewing sections to more up and down simulating the flight of a bird orinsect.

Having thus described. the invention what'- is claimed as new anddesired to-be sec'uredbyiet ters Patent is:

a toy, a pair of handles, a swivel pin pivota'lly connecting saidhandles together interme= digits of their ends, one end of said-handlesadapt ed to be gripped in the users hand for causing pivotal movement ofthe handles, a pair of U- shaped reinforcing members including a pair ofstems extending outwardly of a base member and having bearing supportson the outer ends of the stem members, short extensions on each stemextending at an acute angle thereto and having bearing supports on theouter ends thereof, a first section of a bird or insect simulating wingmembersecured to each of'said reinforcing memb'ersl. ase'obnd Section ofasimilar wing member secured to said extensions, 2. first through boltpivotally connecting the bearing supports on the stems of thereinforcing members, a second thrlfllgh bolt passing through the bearingsupports on each extension for pivotally connecting each extension tothe other end of said handles, spring. means connected to said first andsecond through bolts, so that upon compression of the one end of saidhandles said wings will move up and upon release of the one end of saidhandles said spring means will cause said Wings to move down intoriormalposition; and said spring means embod ing a coil spring circum oseu' onsaid first said through? bolt.
